Claims

[Scope of utility model registration request]

9. The raw cloth is wound up by a raw cloth take-up roll having a built-in coil spring that always works in the direction of winding up the raw cloth, and when the raw cloth is unrolled, the raw cloth take-up roll resists the force of the coil spring at a desired position. In the roll screen, the raw cloth is stopped at a desired height by a stopper that stops the rotation of the raw cloth, and an initial winding drum for giving an initial winding to the coil spring is connected to one end of the raw cloth winding roll. one end of the coil spring is locked to the inner surface of the raw cloth take-up roll, and the other end of the coil spring is locked to the first winding drum. In order to form a groove cut in the axial direction on the facing end surface of the raw cloth winding roll, and to rotate the initial winding drum and stop the rotation while applying the initial winding to the coil spring. A roll screen characterized in that a locking piece that removably engages with a locking portion formed on the first winding drum is slidably mounted in the groove.
